Plant anatomy is the part of botany, which is concerned with the study of the internal structure of plants. It is called as Phytotomy. Understanding plant function is the key to enhancing crop production, producing medicines, preserving plant biodiversity. Plant metabolism is known as the complex of chemical and physical events of respiration, photosynthesis, and the synthesis and degradation of organic compounds. Phytology deals with the scientific study of plants.Plant Hormones are chemical messengers that are made in one place in the plant body and deliver their message in a totally different place in the plant body. There are many hormones such as Auxin, Gibberellin, Cytokinin, Ethylene and Abscisic Acid by which each hormone is responsible for each function in plants. The drought signaling in plants is done by Abscisic acid during the time when there is stress on water availability. These hormones found only in small concentration but plays a vital role in plant growth, metabolism, aging etc. and study of these hormones are necessary to know well about plants.
